This is a repeat of several similar questions, but all of the answers I've seen are 7-10 years old an no longer relevant, as dart has since come out with null safety.
Currently, I am building a Chrome Web Extension in Dart and using some Dart interop libraries like the package:js/js.dart
and dart:js
. I am trying to retrieve a key-value pair from the Chrome Storage API, and can successfully do that with the following:
var test = context['chrome']['storage']['local'];
test.callMethod('get', [
['r'], // Assume that this is already stored in chrome storage via chrome.storage.local.set()
(Object result) {
_getCallback(result);
}
]);
void _getCallback(dynamic stuff) {
JsObject obj = stuff as JsObject;
print(obj.toString());
}
The issue is that I am unable to see anything inside of obj
, as it just returns a JsObject
type. Is there a proper way in modern dart to retrieve what i need from this object? Thanks in advance!
CodePudding user response:
You can convert it to a JSON (JavaScript Object Notation) string
JSON.strigify(object) // Javascript
save the string in the storage and then retrive it from the storage and parse it from Dart
import 'dart:convert'; // Dart
JSON.decode(string)
This answer may help for parsing the JSON from dart.
